Super 3 Gun (S3G) Trigger

Full Description

The Geissele Super 3 Gun (S3G) is a semi-automatic, hybrid cross between a single-stage trigger and a traditional 2-stage trigger. Its robust feel and light pull weight, combined with a lightning-quick reset, make this trigger ideal for any 3 Gun competitor.

Additional Information

Notes The S3G trigger has a very short, light pull and reset. We do not recommend it for duty use, bench rest, accuracy work or shooting small groups. It is designed for close course competition use where rapid target engagement with quick follow up shots are required. * COLT 901 RIFLE USERS PLEASE SEE ARMORS TOOLS FOR PINS (PART# 02-269) THAT WORK WITH THE WIDER RECEIVER.
Size Standard Mil-Spec Pin
Intended Function Target Shooting, Competition
Trigger Bow Type M4 Curved

Even nicer than the SSA-E - chris

I previously reviewed the SSA-E on there saying it was the best trigger in the world or something... I lied. I won one of these from Cola Warrior West IV last month, and it is incredible. It comes with two sets of springs (I have the heavier installed and it is still lighter than my SSA-E)

I love the 1/2 stage hybrid, it's a bit harder to stage but it gives me more of a surprise break, which nets me better results. It feels maybe slightly less crisp than the SSA-E but I think that is due to the less discernable wall between the stages. I prefer this trigger on a long range and/or fun gun. I think the SSA-E would be a better choice for a "duty" or more serious gun

Awesome Trigger - Andy

I bought a rifle about a year ago and it came stock with a S3G Geissele trigger. This trigger is probably by far the best I have ever used. I didn't think much of it when I first got it and shot it but when I started shooting all my other friends rifles, their triggers we're JUNK. Makes me really appreciate the design and engineering that goes into these triggers. Liked it so much I bought me a flat trigger 3g for my other build. 5 stars and 2 thumbs up.

Doesn't get much better than this! - Janice

I have two of these for about 3 years now. One on my Daniel Defense 556 and the other one on a 300 AAC Blackout SBR. Love these triggers as they have a very smooth pull with a left off that you would be hard pressed to feel it coming. The short reset allows for very fast followup shots. If you understand the physics of an AR platform you find this very easy to bump fire from a standing shoulder fired platform. I highly recommend this to anyone!

Buttery Smooth - Matthew

This thing is incredible. The best way I've heard it described is "a single stage trigger is like kicking open a door. A two stage is like walking up a small hill then kicking open a door. THIS trigger is like walking up a small hill and that's it." There's no discernible break or build up. Just a glide and sometime right before it stops, the weapon discharges. It's amazing. Tactile and audible click on reset too. This trigger is FAST.

Excellent trigger! - Snowcatt

My LR308 trigger began to fail with the first shot, and by the time it had 200 rounds through it there was a ledge so big you almost couldn't pull the trigger. No problem, let's upgrade

High Quality - Brad

I have been using the S3G trigger for just about a year now and have been nothing but impressed. Smooth quick release and reset. Definitely a major improvement over stock triggers and at the top of the custom triggers! I look forward to my next trigger purchase from Geissele and will be updating all my AR's with Geissele products!

Work of Art - Paul

This trigger looks like a work of art. It functions even better than it looks. Top notch craftsmanship!! I would recommend this everyone with an AR platform.

Awesome - Robert

Put this in a CMMG 9mm Pistol and wow. This setup immensely increased trigger reset speed. Don't normally bump fire, but have using a rubber band. With the S3G trigger you really have pay attention not to bump fire.
